The spell that Seamus Finnigan uses to try and turn his goblet of water into rum. Much like everything else that he tries to put spells on, the water explodes in his face.
Seamus: Eye of rabbit, harp string hum, turn this water into rum!
Harry: Ron, what's Seamus trying to do to that glass of water?
Ron: Turn it to rum. Actually managed a weak tea yesterday, before--
BOOM

Get the Humming birdsmug. A Westchester County, New York correctional facility with a less-intense level of confinement than its full-blown "vocalized music and lyrics" counterpart.
Maybe da only drawback of being incarcerated at Hum Hum Prison is dat you are merely bored (i.e., you have a "ho-hum" lifestyle), rather than actually feeling confined and stagnant.
